Wright, 2013
Acute Asthma Exacerbation
� Measure Spirometry vs. Peak Flow
� FEV1 is most important number– >80% predicted
– 50% – 79% of predicted
– < 50% of predicted
http://www.nhlbi.nih.gov/guidelines/asthma accessed 06-01-2012
19 Wright, 2013
Spirometry Results
� FEV1 = 62% of predicted
� FEV1/FVC = 90%
� What does this mean for our patient?
20
Wright, 2013
Acute Asthma Exacerbation
� Inhaled short acting beta 2 agonist: – Up to three treatments of 2-4 puffs by MDI at 20 minute intervals
– OR a single nebulizer every 20 minutes up to 3 over the course of one hour
� Can repeat x 1 – 2 provided patient tolerates– Xopenex 1.25 mg nebulizer
– Reassess spirometry or peak flow after
http://www.nhlbi.nih.gov/guidelines/asthma accessed 06-01-2012
21 Wright, 2013
Prednisone
� Multiple products available
� Prelone, Orapred, Prednisone
� Prednisone 10 mg 1 po bid x 3-10 days
� 1 mg/kg/day – maximum in children
� Adults; can use up to 120 mg per day
� No taper necessary
http://www.nhlbi.nih.gov/guidelines/asthma accessed 06-01-2012
22
Wright, 2013
Home Nebulizer
� May be important to order the patient a nebulizer to be delivered to his/her home
� Will be set up by a respiratory company
� Patient and parent will be taught appropriate utilization
23 Wright, 2013
Patient Education
� Have plan in place for next URI
� Preventative therapy?
� Environmental modification
� Daily peak flows

Wright, 2013
Management of Moderate Exacerbations: Response from
Emergency Treatment
� Good Response
– Symptom relief sustained x 1hr; FEV1 or PEF ≥ 70%
– D/C home
– If already on inhaled corticosteroid, double dose of steroid x 7-10 days
– Continue SABA & oral corticosteroid
– Patient education / asthma action plan
25
http://www.nhlbi.nih.gov/guidelines/asthma accessed -02-15-2013
25 Wright, 2013
Management of Moderate Exacerbations:
Response from Emergency Treatment
� Incomplete Response– Mild-moderate symptoms, FEV1 or PEF 50-69% x 1 hour– SABA, oxygen, oral or IV corticosteroids– Can D/C home if stable– Individualized decisions re: hospitalizations
� Poor Response– Marked symptoms, PEF <50%– Repeat SABA immediately until ER evaluation– ED / 911
26

Key Differences in the EPR-3 Report
� Point of discharge
– FEV1 or PEFR ≥ 70% predicted
– Response sustained 60 minutes after last treatment
– Normal physical exam
� Continued ED treatment needed
– FEV1 or PEF 40-69% predicted
� Consider adjunct therapies; 911, hospitalization
– FEV1 or PEF <40% predicted

Stridor
28
Wright, 2013
Stridor
� Upper airway obstruction
� Getting air in more of a problem than getting air out
� Harsh inspiratory noise
� Created by an obstruction of the nasopharynx, pharynx, glottis, subglottis, or supraglottis
http://www.aafp.org/afp/1999/1115/p2289.html accessed 06-01-2012http://emedicine.medscape.com/article/995267-overview accessed -06-01-2012
29 Wright, 2013
Stridor
� Few conditions in pediatrics are as emergent and potentially life threatening as an upper airway obstruction
� Rapid identification and treatment is essential

32
Wright, 2013
What Is It?
� Peritonsillar abscess is the most common deep infection of the head and neck that occurs in children
� It is typically formed by a combination of aerobic and anaerobic bacteria
� Begins as a superficial infection and then develops into a cellulitis/abscess of the tonsillar region
� Multiple antibiotics are thought to increase the risk for the development
http://www.aafp.org/afp/1999/1115/p2289.html accessed 06-01-2012http://emedicine.medscape.com/article/995267-overview accessed -06-01-2012
33 Wright, 2013
Peritonsillar Abscess
� Generally begins as an acute febrile URI or pharyngitis
� Condition suddenly worsens– Increased fever
– Anorexia
– Drooling
– Dyspnea
– Trismus
http://www.aafp.org/afp/1999/1115/p2289.html accessed 06-01-2012http://emedicine.medscape.com/article/995267-overview accessed -06-01-2012

Wright, 2013
Buchner BS. Anaphylaxis. N Engl J Med 1991;324:1785–1790.47
Step 2
� Call 911
– Perform after administration of epinephrine
Wright, 2013
Buchner BS. Anaphylaxis. N Engl J Med 1991;324:1785–1790.48
Wright, 2013 9
Step 3
� Administer diphenhydramine
– Preferably liquid or chewable
– If not available, tablet is okay
– Should be used in addition to the epinephrine, not in place of it
Wright, 2013
Buchner BS. Anaphylaxis. N Engl J Med 1991;324:1785–1790.49
Step 4
� Additional measures while awaiting EMS

� Cough syncope:
– Rare
– Cough causes the patient to Valsalva
� Micturition syncope:
– More common in men
– Typically occurs at night; often associated with alcohol ingestion
– Most likely the result of a vasodepressor reflex triggered by a sudden decrease in bladder pressure
– Treatment: urinate in the sitting position; alcohol avoidance
